That's genuinely exciting, hitting the point where donations cover a Steam release is a real milestone, and honestly a strong signal that people believe in what you're building here, not just playing it passively.
If you do end up moving forward with it, that's actually a great window to start thinking about visibility ahead of time, building some momentum on itch now so there's already an audience ready to follow you over once Cycle lands on Steam. Cultivation incrementals especially tend to spread hard through word of mouth and community once the right people discover them.
Since you mentioned already having a Steam developer account from your other project too, sounds like you're thinking long term here. If it's ever useful, I do social media management and video content for indie devs, happy to help build that visibility now so you're not starting from zero whenever the Steam move happens. just wanted to mention it given where things are headed.
